SPRING `BED-BOTTOM.

SPECIFICATION forming' part of Letters Patent N o. 657,551, dated September 11, 1900.

Application filed November 4, 1899. Serial No. 735,827. (No models i To all whom, vif may concern:

Be it known that I, HOWARD E. LAUGHLIN, of Cleveland, Ohio, have invented certain new and useful Improvements in Spring Bed-Bottoms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will 'enable others skilled in the art to which it pertains to make and use the same.

My invention relates to spring bed-bottoms, especially such as employ spiral springs in their construction, which are tied together at their top or at both top and bottom by means of wires extending from side to'side or from end to end of the frame.

My invention consists in the method of securing the tie-wires to the several springs, all of which will hereinafter fully appear, and be set forth in the claim.

In the drawings, Figure 1 is a plan view of a section of a spring bed-bottom, illustrating the application of my invention. Fig. 2 illustrates more clearly a modification of my lock as used in-connection with crimped tie-Wires. Figs. 3 and 4 also illustrate modifications of the lock when used in connection with other tie-wires.

A represents spiral springs of the usual construction, such as are employed in this class of bed-bottoms.

B represents the upper or lower convolutions of the springs, and C and D represent the tie-Wires and cross-Wires, respectively.

As illustrated in Figs. 1 and 2,' I prefer to form both the tie and cross wires with a series of equidistant crimps c and cl, running the entire length of the wires, andthus having elevations and depressions contiguous or in close proximity to each other. The objectof thus forming the said wires is to permit them to be used in assembling the springs of different-sized bed-bottoms, Where the springs are spaced at different distances from each otherf Also by forming the wires crimped they give or stretch to a certainextent lengthwise, but are more stiif vertically, thus helping to sustain any weight and assisting the spring A.

I prefer to construct the lock for securing the springs positively to the tie-Wires as follows: The end of the convolution B is bent upon itself, so as to-form a hook b. Directly opposite the hook portion b the convolution is bent, as at e, thus forming a seat for the tie-wire C, which passes'through said bend.

(See Figs. 2, 3, and 4.) In order to secure the tie-wire C and the springs A, the free end b of the hookb is 'passed under the convolution 'of the spring to the rear of the bent portion I) (see Figs. l, 3, and 4, respectively) and thence upward and over the tie-wire C, when it is bent in a suitable direction downwardly, thus locking the parts securely together (see Figs. 3 or 4) and preventing them from slipping one on the other. The tie-Wire `O is crimped, and said crimp engages one or the other of the spring-wires, as illustrated in Figs. 3 and 4, or where the tie-wire is crimped its entire length, as illustrated in Figs. 1 and 2, more than one of the crimps engage the spring-wire. In Fig. 2 of the drawings I have shown the hooked end of the wire as passing over the convolution of the spring, thence under the cross-Wire or tie-Wire at each side of said convolution, and having its free end Abent slightly upward and t-o one side. This construction may be employed as a modificationof that hereinabove set forth and will accomplish the same purpose in substantially the same manner.

It will be seen that the wire C may run either crosswise or lengthwise of the frame (not shown) and that the Ycross-wires D run at right angles to the said tie-wire C, which allows the said tielwires and cross-wires to engage at the center of each spring, as at f, and to engage the outer convolutions at three points a, et', and a2 besides at the lock, and when crimped wire is used, as illustrated in Figs. 1 and 2, the springs are held very rigid and made to move in a direct vertical line Without buckling It will be also understood that both bottom and top of singledeck bottoms may be secured in the same manner by tie and cross wires and that doubledeck bottoms may also be constructed by means of my invention, as may be clearly seen by any person skilled in the art.

By the term single-deck bottoms will be understood bed-bottoms having but one set of horizontally-arranged springs secured together at their tops and bottoms. By the term double-deck bottoms will be understood bed-bottoms which have two sets of horizontally-arranged springs, one above the other,
